Light Fermion Mass Effects in e+e- -> 4 Fermions
Jiri Hoogland, Geert Jan van Oldenborgh
Abstract
We investigated the effect of the light fermion masses on cross sections for e+e- into 4 fermions in the Fermion Loop scheme defined in hep-ph/9612260, and approximations to it. The effects are found to be very small, except of course in the collinear region of single W-boson production where the electron mass acts as the cut-off.
